Expansion technologies to achieve dehydrated and crispy food

At AZTI-Tecnalia we support new product development in the food industry through new technology application such as Controlled Instantaneous Decompression (CID) and microwave technology.

When applied to a dehydration process these technologies are capable of expanding food of meat, fish and vegetable origin Innovative dehydrated products can be obtained with attractive appearance (expanded and aerated) and crispy texture which is an improvement when compared to elastic or compact textures of dehydrated products already existing on the market. Furthermore, these technologies enable expanding food without the need for frying in oil and therefore also improving their nutritional profile.hr_invisible]
